'VULCANIZER.

Specification of Letters Patent.

Application ledAugust 10, 1918. Serial No. 249,306.`

lo all whom t may concern.'

Be it known that I, ALPHnUs FAY, a citizenozt the United States, and a resident of Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Vulcanizers, of which-the following is a specification.

My invention relates to portable vulcanizing apparatus for application of patches to the inner tubes of pneumatic tires, or to similarr articles which may be patched in suchv manner. 1

The object of my invention is to simplify the construction and add to the convenience of use of apparatus of this character.

Iny the drawing:

As shown in Figs. l and 2. the relatively wide and flat base-plate 1 has xed `in it and extending upward from it near one end an eye 2, and tired in it and extending up from it near its other end astud 3, which' which has the eye 2.

nThe beam l comprises a relatively short horizontal middle part 5 and parts 6 and 7 sloping from it downward toward the respective .ends of the base-plate 1 and teris bent over horizontally toward the end Patented Nov. 19., 1918.k

minating in short substantially horizontal parts 8 and 9, respectively, near the ends ot the base-plate 1.

The downwardly inclined part 6 is shorter than the downwardly inclined part 7, and its short horizontal end part `S has fixed in it and depending from it an eye 10 linked in the eye 2 ot the base-plate 1so thatA an articulated connection is made at this end between the beam 4A and thefbase-plate 1, which will permit the beam l to be swung into a great variety of positions relative tok thebase-plate, as instanced in Fig. 2. The other orlonger part 7 has its short .end part 9 slipped under the bent stud 3 to place the device in operative condition.

rEhe thumb-screw y11 passes down through the horizontal part 5 of the beam 4, and has swiveled on its loweiend, the yoke bar 12, which comprises kthe long straight part 13 with transverse extensions .or .arms 14 coincident with the connection of the screw 11 to the bar ,12 and which have downturned end parts 15. The yoke-pieces 16 are slidable longitudinally of the `part 13 at respective sides of the arms 14, and each yokepiece is substantially in the form of an angle-bar bent around into U-shape, with one flange extending downward and the other extending inwardly of the U, and with the terminal parts integrally joined by a strip 17. The downwardly extending flange at the bottom of the U has a transverse slot 18, and the end of the bar 13 extends through this slot 18, and the strip 17 is bent down at the middle under the bar 13. These yoke-pieces 16 are 0i approximately the same transverse extent, so that the downturned end parts 15 of the arms 14 are substantially in line with the downwardly eX- tending flange at the terminations of the yoke-pieces 16. The ends of the har 13 are enlarged slightly so that -they will not pass through the slot 18; thus preventing the yoke-pieces 16 from sliding completely off the bar 13.' i

Such a yoke yas this is used in conjunction with a flat plate 19 which is placed directly i,ees,ces

on the patch 2O which has been properly applied to the rent in the inner tube 2l, or other article to be patched. Diilerent sized rents, and diierent sized plates or the saine plate 19, may be used for the different sized patches. The important requirement is to have especially l'irm clamping around the edges or' the patch. in this yoke, the yokepieces i6 may be slid out as tar required on the bar 3 to cause them to lit different sized patches, in accordance with the requirements just referred to.

ln the inodiiied yoke et Figs. et, 7, 8 and 9, the yoke bar 22 is simply straight and swiveled to the screw near its center, and each yoke-piece 28 comprises simply a tlat iJ-shaped part with its terminals integrally joined by a dat strip Qd which has a slotted lug Q5 bent up from it while a similar lug 26 is bent up from the bottom or' the li, and the bar Q2 extends through the slots in these lugs 25 and Q6 with its end parts enlarged to prevent the pieces :23 from sliding entirely oli the bar.

rlhis modiiied adjustable yoke is used in connection with a pan Q7, different sizes oit which may be used with di'lierent sized patches, and calling for adjustment of the yoke pieces 23 along the bar toproperly bear on the rim of the particular sized pan used. The extreme inward adjustment is seen in Fig. d, and the yoke is seen adjusted :tor a longer pan in Figs. 7, 8 and 9.

ln either case, a suitable combustible :28 `is suitably placed inside the yoke over the plate 19 or pan 27, as the case may be, which, when it burns, will transmit heat through the plate 19 or pan 27 to the patch 20.

ln the modiiied device of Figs. 5 and 6, the base-plate l has upwardly extended eyes 29 at both ends, and the beam 3G is simply straight, and has extending down from one end part, a stud 31 with an eye on its lower end linked in the eye 29 in the adjacent end of the baseplate l. At the other end, the bar 80 has an eye 33 extending downward, and a hook 3a: swiveled in the eye 29 at that end of the baseplate and may engage in the eye ot the beam 30.

The yoke and associated parts are as shown in Figs. l, 2 and 3; but it will be understood that this device mayhave the yoke and other parts, as shown in Figs. l and 7.

In these examples of Figs. l, 2, 5 and e, the more or less articulated connections between the beam and the base-plate hold the beam firmly enough to permit the screw ll to exert the required pressure through the yoke and associated parts upon the patch; and at the same time the device is readily opened for placing the article to be patched upon the base-plate, and to allord plenty ot room for adjusting the patch and the plate 19 or pan 27, as the case may be. rlhis is clearly indicated by the dotted lines in Fig. Q, and it will be understood that the device ot Figs. 5 and 6 may be opened in substantially the same way. Either one of the devices collapses or folds together rather coinpactly for shipping and storage in the store r in the users tool kit. lil/'hen the device et Figs. 5 and 6 is collapsed as shown 1n Fig. G, the hook 3st may be again hooked in the eye 83 to hold the device in its collapsed condition.

ln the modification of Figs. 8 and 9, the i beam 35 is similar to that of Figs. l and Z, but its downwardly extended part 36 is relatively longer than the part 6 of the other example, and has its short horizontal end part 37 pivoted to the base-plate l, so that the beam may swing substantially only in the plane of the base-plate. The other end of the beam engages under the stud 3 Vof the base-plate. as in Figs. l and 2, and its parts are thererore given the same reference nurnerals. rlhis example has an advantage over the'precedingY ones in that it is more selfk sustaining when opened, as shown in Fig. 9, but is not so convenient because it cannot be collapsed.

ln any of these examples, it will be noted that the base-plate l is a simple flat plate, and the beam is a plain bar with very simple bends, and the only other parts of the clamp frame are thus riveted onto the beam or the base-plate, as the case may be. 'lhis makes this part of the device very inexpensive. rlhe adjustable yoke is also very simple and inexpensive and easily adjusted, and the entire construction in any example is such as to adord a very inexpensive and convenient vulcanizing apparatus for small patches.

Wille certain constructional details are deemed preferable in connection with my invention, and l have shown and described these rather specifically in elucidating the construction and use ot' my invention, as is required, l do not wish to be understood as being limited to such precise showing and description, but having thus fully described my invention, what l claim as new and de-V sire to secure by Letters Patent is:
